Comparison of chemiluminescence and absorptiometry in enzyme immunoassays for protein quantification

The use of chemiluminescence in competitive binding assays for human serum albumin, human alpha-fetoprotein and human immunoglobulin G and in double antibody sandwich enzyme immunoassays for cytomegalovirus and herpes simplex virus increased the sensitivity of the detection of antigen or antibody 16- to 95-fold above that obtained by conventional absorptiometric methods.     

Brain chopping: A new method for the rapid removal of newborn rat brain

Summary A new multi-bladed air-driven guillotine is described. This device removes newborn rat heads and slices them into several thin wafers, which facilitates freezing and permits easy regional dissection.Supp. in part by U. S. Public Health Service Grant. AA-01391.     

The effect of oxine-5-sulphonic acid on the hepatic drug metabolism in the rat

Summary Oxine-5-sulphonic acid inhibits the metabolism of aminopyrine in the rat liver in vitro. The characteristics of this inhibition vary according to whether the oxidativeN-demethylation of the substrate is determined by the formation of the metabolite 4-aminoantipyrine or by the production of formaldehyde.
